Title: Improvements in and relating to methods and systems of treating products with electrical currents or fields to produce more valuable products
IPC: A61N1/40
Filed: 1946-08-12
Abstract: Alterations in biological processes are produced by treating substances with an electric field of above 20 volts per centimetre strength in pulses of less than 5m  seconds so that the said field does not produce secondary processes to a detrimental extent either directly or indirectly by heating or by electrolysis.  The field direction is alternated to prevent electrolysis and may be attained by two current impulses following quickly upon each other in opposite directions or by a condenser being charged and then discharged through the substance. An alternating current of rectangular shape or a modulated high-frequency alternating current is used and the fields may pass through the substance in different directions at right angles to each other.  When a liquid is treated it may be led between a pair of electrodes giving a current in one direction then led through another pair of electrodes giving a current in the opposite direction, and cooling of the liquid may be effected between the pairs of electrodes.  To increase the duty cycle the liquid velocity is increased.  The high frequency generator is combined with contact means whereby the current produced is periodically interrupted or greatly decreased and the contact means may be a rotating disc, a vibratory contact, a relaxation-generator or a rotating or oscillating mercury jet.  The generator may be controlled by a photo-electric system.  A medium frequency generator may also control the high-frequency generator and is then connected through a modulation coupling.  The high frequency generator is connected to distribution means which may be made up of a mercury jet or of an electron beam switch.  For high tension current impulses the generator is built up of condensers discharged by thyratrons. Radiating dipoles and reflectors may be used.  The method may be used in sterilization, and viruses, toxines, bacteria cultures, tissue cultures and milk may be treated.  Specification 661,651 is referred to.

Title: Photographic Camera Provided with Exposure Meter
IPC: G03B7/099
Filed: 1967-05-25
Abstract: 1,193,123. Exposure control apparatus. NIPPON KOGAKU K. K. May 25, 1967 [May 28, 1966], No.24325/67. Heading G2A. A camera has an through the lens exposure meter having a plurality of light sensitive elements one of which measures the brightness of the whole image area and the other which measures part only of the image area, a member being operable from outside the camera so that either one or the other or both the elements may be connected to the exposure meter circuit the difference between the resistance in circuit when one light sensitive element is in circuit and when both elements are in circuit being connected by compensating means. As shown, the camera is a single lens reflex camera having photo-conductive cells 9 and 10 of cadmium sulphide positioned at opposite sides of the view finder light path. The illumination of the cells 9 and 10 is approximately proportional to the illumination on the whole area of focussing plate 4. A third photo-conductive cell 12 is fixed at the end of a lever 13. A knob 25, on a slidable plate 19, rotates a lever 18 clockwise when actuated in the direction of the arrow Y to position cell 12 at the centre of focussing plate 4 and cause a contact 32 to engage a contact 33. A galvanometer 39 is biased by a spring 40 to rotate counter-clockwise. A painter 43 projects into the view finder light path shutter speed setting ring 57 carries a brush engaging a resistance 49. A contact arm 54 on a diaphragm setting ring 53 engages resistance 49 while a film sensitivity scale is formed on a ring 50 connected to ring 53 by a clickstop. Resistance 49 is adjusted by varying either shutter speed or lens aperture to position the pointer 43 at the centre of an indicator 6 . A dial 16 is rotated until a symbol is opposite an indicator mark 58 and then knob 25 is pushed to the right, thus switching cells 9 and 10 out of the circuit and photo-cell 12 in to measure the brightness of part of the image area. When knob 25 is released lever 13 is moved counter-clockwise to remove cell 12 from the light path. Cells 9 and 10 are then connected in parallel with the galvanometer 39 to measure the brightness of the whole scene when knob 25 is again pressed to the right with dial set with a further symbol opposite mark 58, cells 9, 10 and 12 are connected in parallel with the galvanometer 39 to measure the average illumination of the whole image and part of the image. The variation in resistance in the circuit can be corrected for by (a) rotation of the galcanometer (b) by switching in a shunt resistance for the galvanometer (c) by changing the voltage of the supply 48 (d) by providing a bridge circuit into which a compensating resistance may be switched.

Filed: 1971-04-19
Abstract: 1348042 Mixing and discharging slurries MITSUI SHIPBUILDING & ENG CO Ltd 19 April 1971 [24 Aug 1970] 24355/71 Heading B1C In apparatus for forming a slurry to discharge solid material 5 from a tank 1 the latter has a sump 2 and a rotating water jet 4 the angle to the vertical of which is adjustable. High pressure water is supplied by the pump 30 to the jet, and low pressure water by the pump 37 to an inlet 6 and inlet apertures 42 of the sump, and to a jet 43 in the sump which assists discharge thereof into a pipeline 7. Discharge of the tank is begun with the jet 1 vertical and it is gradually lowered in dependence on the height of sensors 45, 50 which successively contact the exposed face and control the speed of the motor 28 which rotates the jet, and a hydraulic cylinder 24 which adjusts the jet angle #, which is maintained at 5‹ to 20‹ less than the face angle °. The sum of low and high pressure water flows is maintained constant but if increased slurry concentration is detected by the sensor 55 the proportion of high pressure water is decreased to reduce the amount of solid removed, and vice versa. If the slurry surface in the sump rises above a predetermined level the detector 58 shuts off the high pressure flow by closing the valve 33, the low pressure flow being thus increased to clear the obstruction.

Abstract: 1414052 Preventing overdischarge of batteries in a standby system GENERAL ELECTRIC CO 24 May 1973 [24 May 1972] 24783/73 Heading H2H A standby power supply system for gas discharge devices such as is disclosed in copending Specification 1,414,051 is provided with means to inhibit operation of the oscillator when the voltage of the standby battery drops below a predetermined value. A battery 18 forming the emergency power source has a potential divider comprising resistors 43, 44 connected thereacross, the common point of the resistors being- connected to the base of a transistor 39. The transistor is normally conductive so as to prevent a capacitor 40 from being charged from a winding 35 on the transformer 15 in the oscillator 19 which is supplied by the battery 18. If the battery voltage falls below a predetermined value the transistor 39 becomes non-conductive, the capacitor 40 begins to charge until it reaches a potential at which a device 41 breaks down causing a thyristor 36 to conduct thereby applying a short circuit across the winding 35 of the transformer 15. This causes the inverter to cease functioning and allows the battery 18 to recover. When the battery recovers sufficiently to break down a Zener diode 45 oscillation of the oscillator 19 restarts.
